    ALSA: hda - Modularize HD-audio driver · 1289e9e8
    Takashi Iwai 提交于
    Split the monolithc HD-audio driver into several pieces:
     - snd-hda-intel   HD-audio PCI controller driver; loaded via udev
     - snd-hda-codec   HD-audio codec bus driver
     - snd-hda-codec-* Specific HD-audio codec drivers
    
    When built as modules, snd-hda-codec (that is invoked by snd-hda-intel)
    looks up the codec vendor ID and loads the corresponding codec module
    automatically via request_module().
    
    When built in a kernel, each codec drivers are statically hooked up
    before probing the PCI.
    
    This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module
    information for each driver, and driver-linking codes between
    codec-bus and codec drivers.
    
    TODO:
      - Avoid EXPORT_SYMBOL*() when built-in kernel
      - Restore __devinit appropriately depending on the condition
